SP111.CIIFICATION forming part f Letters Patent No. 601,584, dated March 29, 1898.

Application led July 23, 1897. Serial No. 645,683. (No model.) i

To a/ZZ whom t may concern:

Be it known that I, TIMOTHY W. MURPHY, of Washington, in the District ot' Columbia, have invented certain new and useful Improvements in Rail-Chairs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which Will enable others skilled in the'art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the .letters of reference marked thereon, which form part of this specification.

This invention relates to certainnew and useful improvements in rail joints and chairs, and has for its objects simplicity, durability, and cheapness in construction, composed of a minimum number'of parts, and sure, quick, and effective in operation.Y Y Y,

A further object of the invention is to provide a chair which can be easily and quickly 4 set without the use of fish-plates, screws, bolts,

or nuts, and one that can be equally as well used with either a metal or wood tie.

A further object of the invention is to provide a chair so constructed that where the several members join the said joints are protected against interference of malicious persons, the working parts all being under cover and out of sight, the opening in the tie being under the chair; or two ties may be used, leaving a space between them. The working parts in this space or opening are hidden from view, and no person can know how they are fastened until he possesses the key to their operation, and they are so arranged and interlocked that they assist each other to hold their proper positions and can only7 be removed in the proper way. i

The invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a central vertical cross-section through one rail, showing the4 invention applied to a wood tie, as on the line o: of. Fig-.3. Fig. 2 is a tallic tie.

locking clamps and brace-plates in operative position, but removed from the tie, the rail not shown. Fig. 5 is an inverted detail perspective view of the locking-plate. Figs. 6 and 7 are detail perspective views of the interlocking clamps.

' Referring by letter to the drawings, a is the base-plate or metallic tie, which is adapted to be used either alone or in connection with a wood tie l).

c is a depression or recess for the reception of the rails CZ.

About the center of the base-plate or metallic tie a is a slot e, to each side of which are the openings e.

Below the slot e on the under -side of the plate or tie a and inside the rail depressionc Vor between the tracks is a box or frame e2,

depending from said tie d to receive the interlocking clamp g. An opening e3 is provided for the reception of the king-pin f, which is forced down through said clamp g and opening e3 when the chairy is set.

g and g are the interlocking clamps, having the depending posts h h', adapted to it into the slot e and openings e', the post hfitting the central slot e, the lips h2 resting in the recess e4, and the edge of the brace-plate g snugly abutting the bevel bead or stay g2. The short posts h' t the openings e', and the lips e3 rest in the recesses e4, thus forming a tongueand-groove joint.

Passing inwardly and snugly fitting the slot e and iiush with the top surface of the depression c is a tongue ,which rests on the support j of the depending block j of the braceplate or the inside member of the interlocking clamp g' and is held there by the pressure of the rail d. The block j also has an inwardly-projecting tongue l7'2,which lits in the slot e and rests on the box or frame e2, having an opening js, corresponding with the opening e3, through which passes the king-pin f, thereby securing the rail d rigidly between the interlocking clamps g g and the baseplate or metallic tie a.

7c is the locking-plate, adapted to it in the 1 IOO m, which lits over and is adapted to secure the clamp g'.

fm is a frame in which the extension fm, snugly fits for the purpose of preventing tampering.

On the underside of the locking-plate 7c is a downwardly-projecting leg k', which rests in the curved end of the tonguej2 of the clamp g' and presses same tightly agai'nst the rail.

Any suitable lock may be employed to secure the locking-plate Za to the tie; but I preferably use a dovetail joint consisting of the dovetail or tapering lugs n and a beveled bar (not shown) which coincides with and is adapted to slide between and be tightly held by said lugs n, or the lock fu and key w may be employed, the lock being secured in the tie below the locking-plate and the key passing up therethrough and operated from above said locking-plate.

This chair is adapted to be used either with metallic or wood ties, and it is constructed without the useof screws, bolts, or nuts; but when the base-plate or metallic tie a is used through the clamp g and said tie a, beneath Awhich and through the pin p is passed a split key p.

The construction and operationof this chair is very simple and is as follows:

The' clamp g is set in position on the outside of the rail on the base-plate d, the depending posts h and h inserted into the slot le and the openings e", the openings e being of sufficient length to allow the lips h2 and h3 to pass down low enough to slide into the rei cesses e4 of the metalli-c tie or base-plate a and pushed toward the rail, the brace-plate pressing tightly against the rails el, iitting snugly between the head and base thereof. The support j is carried directly under the tongue 'i of the clamp g, the tonguej2 resting in the frame or box e2, the openings e3 of the box and js of the tongue jf? registering and i adapted to receive the king-pin f. When the king-pin f is in place, it is readily seen that the rail is rigidly held between the two clamping-plates g and g and the metallic tie or base-plate a. The locking-plate 7c is then adj-usted in the opening Z, bearing directly on the tonguej2 and the upward extension m thereof on the brace-plate between the frame m. The leg k of the locking-plate k rests in the curved'end of the tongue jg, and when the beveled or dovetailed bar is inserted in the way formed by the dovetailed lugs n, cari and interlocked as rigidly as a single piece of metal. This construction of interlocking clamps may be used to as much advantage in `other structures than rail-chairs-for indeparting from the spirit and scope of the invention. Hence I do not wish to limit myself to the exact construction herein set y forth, but consider myself entitled to all such changes as fall within the spirit of the invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters i Patent of the United States, is-

l. A rail-chair comprisingfthe base-plate or metallic tie, having openings, clamps having depending posts, adapted to engage said openings, a box or frame beneath said baseplate having an opening and a pin adapted I to pass through one of the clamps and the I frame, substantially as described.

alone suitable pins p are employed to pass 2. A rail-chair comprising,- the base-plate 1, having a series of openings therein, a depression in the top of said base-plate, clamps having depending posts, lips on said posts engaging said openings, a tongue on one clamp, a

support on the other clamp on which said tongue rests, aframe beneath said base-plate, the inside clamp resting in said frame, a pin passing through said frame and clamp and a locking-plate resting on and covering said pin, substantially as described.`

3. A rail-chair comprising, the base-plate,

a central slot therein, openings in said plate,

a depression in the top surface of said plate,

clampshaving tongues, depending posts from `said clamps having tongues engaging said fslot and openings, a support on the inside `clamp for the tongue of the outside clamp which is flush with the upper surface of the depression in the base-plate for the reception of the rail, a tongue resting inthe box or frame of the base-plate having an opening, an opening in said frame registering with said opening in the tongue adapted to receive a pin, a locking-plate holding said pin in place and locking means for said lockingplate, substantially as described.
